I should be able to piece together a working top loader today. I found a spare motherboard that I can do the bios mod on. I'll let everyone know the results.

I'll have time today to test on a top loader. I hope I didn't sell all my games.
Brian do you feel like doing any tests on your front loader? Name a game that you have if you're interested, preferably one with shit load times.
You mentioned something about solderless method of installing the BIOS, since there's no way I'm doing surface mount soldering what can be done about that? If that doesn't work out, I might ask Hewitson to socket it.

No idea what that is, but its sure as hell not 68k asm.IF SYSTEM_Z
DEPENDANT_ReadController EQU $C09444
DEPENDANT_PostIPLExit EQU $C0A872
ELSEIF SYSTEM_F
DEPENDANT_ReadController EQU $C0B9F6
DEPENDANT_PostIPLExit EQU $C0CF7A

That makes sense. What assembler are you using? I've not seen that sort of syntax before.@Hewitson: the 68k stuff is elsewhere, that's part of the preprocessor. It defines targets for jmp instructions since they were moved around with each system.
